redis配置：
1、在pom.xml中引入Java版本redis-----Jedis

<!-- https://mvnrepository.com/artifact/redis.clients/jedis --><dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.9.0</version></dependency>

2、spring-redis.xml配置

3、redis.properties

redis.hostname=Redis所在服務(wù)器ip redis.port=6379 redis.database=0 redis.pool.maxActive=100 redis.pool.maxIdle=20 redis.pool.maxWait=3000 redis.pool.testOnBorrow=true

JedisPoolWriper.java

package com.mlr.controller.cache;import redis.clients.jedis.JedisPool; import redis.clients.jedis.JedisPoolConfig;/*** 強(qiáng)指定redis的JedisPool接口構(gòu)造函數(shù)，這樣才能在centos成功創(chuàng)建jedispool* * @author xiangze**/ public class JedisPoolWriper {/** Redis連接池對(duì)象 */private JedisPool jedisPool;public JedisPoolWriper(final JedisPoolConfig poolConfig, final String host,final int port) {try {jedisPool = new JedisPool(poolConfig, host, port);} catch (Exception e) {e.printStackTrace();}}/*** 獲取Redis連接池對(duì)象* @return*/public JedisPool getJedisPool() {return jedisPool;}/*** 注入Redis連接池對(duì)象* @param jedisPool*/public void setJedisPool(JedisPool jedisPool) {this.jedisPool = jedisPool;}}

然后我們的Jedis就可以用了，把我們的業(yè)務(wù)邏輯中不需要頻繁更換的數(shù)據(jù)保存到redis中，例如，下部分代碼：

@Transactionalpublic List<Area> getAreaList(){// 定義redis的keyString key = AREALISTKEY;// 定義接收對(duì)象List<Area> areaList = null;// 定義jackson數(shù)據(jù)轉(zhuǎn)換操作類ObjectMapper mapper = new ObjectMapper();// 判斷key是否存在if (!jedisKeys.exists(key)) {// 若不存在，則從數(shù)據(jù)庫里面取出相應(yīng)數(shù)據(jù)areaList = areaDao.queryArea();// 將相關(guān)的實(shí)體類集合轉(zhuǎn)換成string,存入redis里面對(duì)應(yīng)的key中String jsonString;try {jsonString = mapper.writeValueAsString(areaList);} catch (JsonProcessingException e) {e.printStackTrace();logger.error(e.getMessage());throw new AreaOperationException(e.getMessage());}jedisStrings.set(key, jsonString);} else {// 若存在，則直接從redis里面取出相應(yīng)數(shù)據(jù)String jsonString = jedisStrings.get(key);// 指定要將string轉(zhuǎn)換成的集合類型JavaType javaType = mapper.getTypeFactory().constructParametricType(ArrayList.class, Area.class);try {// 將相關(guān)key對(duì)應(yīng)的value里的的string轉(zhuǎn)換成對(duì)象的實(shí)體類集合areaList = mapper.readValue(jsonString, javaType);} catch (JsonParseException e) {e.printStackTrace();logger.error(e.getMessage());throw new AreaOperationException(e.getMessage());} catch (JsonMappingException e) {e.printStackTrace();logger.error(e.getMessage());throw new AreaOperationException(e.getMessage());} catch (IOException e) {e.printStackTrace();logger.error(e.getMessage());throw new AreaOperationException(e.getMessage());}}return areaList; }
